Abstract

PROBLEM TO BE SOLVED: To provide an electric connection structure with a superior function of absorbing the positional shift of an electric connection between an coil unit and a connector unit. SOLUTION: A terminal metal fitting 35 includes a metal fixture 36 secured to an electric wire 32 (conductive member) and fixed onto a connector unit 20 and movable metal fitting 37 capable of floating perpendicular in the direction of assembling both units 10, 20 while keeping contact with the metal fixture 36. When a positional shift between a terminal portion 16 and a terminal metal fitting 35 occurs during assembling both units 10, 20, the movable metal fitting 37 of the terminal metal fitting 35 is displaced and thus aligned to the terminal portion 16 by absorbing the positional shift, so that the terminal portion 16 is fitted to the terminal metal fitting 35 without hindrance.

[Invention of Claim 3] When the movable bracket moves freely to correct the positional deviation from the terminal portion, the movable bracket may float while changing its direction obliquely without moving in parallel while maintaining a fixed posture. In this case, since the terminal portion has a circular cross section, the movable bracket changes its posture around the terminal portion. Therefore, the amount of elastic deformation of the elastic contact piece is kept constant, and fluctuation of the contact pressure between the terminal portion and the movable fitting can be avoided.

The elastic contact pieces 50 are formed by being deformed so as to rise while being made to rise, and both ends of the slits 49 are bent so as to form the square rising portions 51 so that the parallel contact rising ends of both elastic contact pieces 50 are formed. The shape is such that the distance between the edges 50A is smaller than the outer diameter of the terminal portion 16. The rising portions 51 are located close to both sides of the rising edge 50A of the elastic contact pieces 50, and the interval between the rising portions 51 is set to be larger than the outer diameter of the through hole 30. The rising portion 5 is moved while the elastic contact piece 50 is approached.
By forming 1, the movable fitting 37 becomes circular in plan view.

き上がることを規制する。A pair of elastic connecting portions 52 are formed on both sides of the elastic contact piece 50 in the direction orthogonal to the rising portion 51. The elastic connecting portion 52 is formed by a well-known processing method called punching out, protrudes upward in a bridge shape supported at both ends, and has an embossed portion 52A formed on the upper surface thereof. The elastic connecting portion 52 can be elastically deformed so as to be crushed downward, and its height in a free state is set to be higher than the lower surface of the upper plate 38. Therefore, the movable fitting 37 is connected to the fixed fitting 3.
In a state where the embossed portion 52A is accommodated in the elastic plate 52, the embossed portion 52A is brought into elastic contact with the upper plate 38. The elastic connecting portion 52 allows the movable bracket 37 to move in a two-dimensional direction (a direction orthogonal to the direction in which the units 10 and 20 are assembled). (In the direction along the mounting direction).

When assembling the connector unit 20 to the coil unit 10, the housing 21 is placed on the flange 14 </ b> U of the coil 12, and the housing 2 is positioned so as to correspond concentrically to the through-hole 30 by positioning means such as unevenness (not shown).
1 and position both units 1 by means such as bonding.
0 and 20 are fixed. At this time, as the housing 21 is mounted on the flange portion 14U, the five terminal portions 16 are interrupted between the elastic contact pieces 50 of the corresponding movable fitting 37 through the through holes 30 and the communication holes 44, respectively. Double elastic contact piece 5
0 is elastically expanded and deformed. As a result, the elastic contact piece 50 squeezes the outer peripheral surface of the terminal portion 16 from both sides and connects with a predetermined contact pressure. At this time, both elastic contact pieces 5
The elastic deflection amounts of 0 are the same as each other.

1 is displaced, or the movable bracket 37 is displaced in the fixed bracket 36 (in the low-back space 48). As a result, the movable bracket 37 is largely misaligned with respect to the terminal portion 16 (position displacement). ) May be fitted. When the direction of misalignment of the movable fitting 37 with respect to the terminal portion 16 is only the vertical direction in FIG. 6, the terminal portion 16 cuts into almost the center of both elastic contact pieces 50, so that the terminal fitting 35 is left as it is. At this position, the terminal unit 16 is fitted. At this time, the terminal portion 16 is pinched at a position shifted to the side of the rising edge 50A of the elastic contact piece 50. However, since the elastic bending amounts of the two elastic contact pieces 50 are the same, a predetermined contact pressure is secured. You.

At this time, the distal end of the terminal portion 16 comes into contact with the curved surface of the elastic contact piece 50, so that the movable bracket 37 is displaced in the left-right direction in FIG. It will be located in the middle of 50. Thereby, the misalignment is corrected, and the two elastic contact pieces 50 pinch the terminal portion 16 with the same contact pressure.

可能である。Further, when the misalignment direction is the oblique direction in FIG. 6, the misalignment in the same direction is corrected by displacing the movable bracket 37 in the left-right direction, and the terminal portion 16 is connected to the two elastic contact pieces 50. It is pinched at a position between the upper and lower sides. As described above, in the present embodiment, the terminal fitting 3
5 has a two-piece structure of a fixed metal fitting 36 and a movable metal fitting 37, and the movable metal fitting 37 can move freely in the direction orthogonal to the mounting direction of the two units 10, 20, so that the two units 10, 20 are assembled. In this case, the terminal 16 and the movable bracket 37
Is displaced, the displacement is corrected by the movement of the movable bracket 37, so that the movable bracket 37 is aligned with the terminal portion 16, so that the terminal bracket 35 and the terminal portion 16 can be fitted without any trouble. In addition, since the displacement is absorbed not by elastically deforming a part of a part but by freely moving the independent movable bracket 37,
The moving distance, that is, the position deviation size that can be absorbed can be arbitrarily set. Therefore, it is possible to cope with the case where the accumulated tolerance due to the parts and the assembly of both units 10 and 20 is large.

との接触圧の変動を回避することができる。When the movable fitting 37 is displaced, the elastic connecting portion 52 is slidably in contact with the upper plate 38 while maintaining the contact pressure due to its elasticity.
And the movable metal 37 maintains the contact reliability. further,
When the movable bracket 37 moves to correct the positional deviation from the terminal section 16, it is conceivable that the movable bracket 37 moves while changing its direction obliquely without moving in parallel while maintaining a fixed posture. In this case, if the terminal portion has a plate-like shape, the amount of elastic bending of the elastic contact piece 50 becomes large when the terminal portion is inclined, and the contact pressure may become too large. However, in the present embodiment, since the terminal portion 16 is in the shape of a protrusion having a circular cross section, the movable bracket 37 changes its attitude around the terminal portion 16 while keeping the amount of bending of the elastic contact piece 50 constant. become. Therefore, the terminal portion 16 and the terminal fitting 35
Fluctuation of the contact pressure with the contact can be avoided.
